System and Method for PWM Control of a Video Display Screen

2. The PWM control system of claim 1, wherein the scan multiplexing control information is configured to cause the scan-multiplexed LED driver to activate each LED scan line for the same duration.

4. The PWM control system of claim 3, wherein the duration of the period when the shutter of the camera is open is an exposure period for a single scan line of the camera.

5. The PWM control system of claim 3, wherein the PWM cycle duration is less than or equal to the frame period.

6. The PWM control system of claim 5, wherein the camera characteristics further comprise a camera sensor readout speed, the PWM cycle is fully or partially repeated during the frame period, and a final repetition of the PWM cycle is terminated after a scan period for a final scan line of the camera, based on the camera sensor readout speed.

7. The PWM control system of claim 3, wherein the PWM cycle duration is less than or equal to one-half the frame period.

9. The PWM control system of claim 8, wherein a phase of the PWM cycle is based on information relating to a PWM implementation of an LED driver of the video display.

10. The PWM control system of claim 9, wherein the subset of the PWM cycle is configured to include pulses of different lengths.

11. The PWM control system of claim 10, wherein the signal is further configured to set a PWM drive level of the LED driver.

14. The PWM control system of claim 13, wherein the video data comprises a test pattern.

15. The PWM control system of claim 13, wherein the camera characteristics further comprise a camera framerate and the PWM timing control is adjusted by adjusting the PWM cycle duration based on the camera framerate.

16. The PWM control system of claim 13, wherein the PWM timing control is adjusted by adjusting the PWM cycle duration to a unit fraction of the period when the shutter of the camera is open.

17. The PWM control system of claim 13, wherein the PWM timing control is adjusted by adjusting the PWM cycle duration to align a subset of the PWM cycle to the period when the shutter of the camera is open.
